Flywheel questions...
The clutch in my A4 12v is gettin a bit weak, so this summer I was planning on replacing it. I figured I might look into gettin a lightened flywheel at the same time. Most are pricey, but I read some old posts about using a lightened 20vq flywheel, and now I'm confused. Will that flywheel or another, work in my 2.8 12v? Anyone have success with this?

20vq wont work because of the spacing of the dual-mass....
Basically your current flywheel is approx 2 inches thick, because of the Dual-mass setup.
The 20vq is approx 1 inch thick.
To make up for the thickness of the dual-mass, Audi extended the bell housing on the gearbox.
This is what I've been told by others. I have not physically attempted to install a 20vq flywheel on my 12v.
However, from looking at 20vq & 12v flywheel side-by side, I can see how the 2 are different, and where this could pose a problem.
My advise, stick with OEM, but maybe upgrade the clutch disk & pressure plate to say level 2 or 3. ;O)<ul><li><a href="http://search.audiworld.com/index.mhtml?q=spec%20clutch&wf=022210&m=al l&cat=010201&dt=range&db=01/01/1999&de=02/25/2005">http://search.audiworld.com/index.mhtml?q=spec%20clutch&wf=022210&m=al l&cat=

20V CQ "should" work as bellhousing is same and flywheel/pressure plate is a taller assembly....
its also a thicker, single mass flywheel that can be lightened even more than the 3B flywheel since its 11lbs (5.5 kilos) heavier than the 3B 17.6lbs (8 kilos) flywheel. And there's plenty of aftermarket disks and pressure assemblies to choose from if you opt for a heavier duty unit.

Ok, I'll look around for a CQ flywheel and experiment with it when I do the clutch. Also a heavy duty clutch, does that wiegh less than stock? Would less mass in the clutch = better performance or is the only benifit better grab?

no but Audi in their infinate wisdom made the pressure plate thicker to compensate... CQ flywheel...
is approximately 1/4"-3/8" thinner than the dual mass B5 12V flywheel and the pressure plate is approx 1/4"-3/8" thicker than the B5 12V pressure plate.
The 3B 20V turbo flywheel is approx 1" thinner than the B5 12V dual mass unit and its pressure assembly is about the same thickness. Thats why its not a good choice for dropping in the B5 12V but the CQ flywheel is.
